The Central Board of Secondary Education (CBSE) says vulnerabilities identified in its OnMark portal are contained and that there has been no compromise of student data or records. According to multiple reports, CBSE has deployed cybersecurity experts and ethical hackers to examine the system further and confirm the scope of the issue. The board also states that it is taking steps to prevent any potential exploitation and to rule out other possible “exploitable weaknesses,” beyond the initially detected vulnerabilities. While the reports describe ongoing reviews and remediation work, they do not provide details on the specific vulnerability types or timing of the discovery. CBSE’s position across outlets is that the situation is controlled and that student information has not been affected. The review process continues as the portal’s security posture is assessed and fixes are applied. The reports collectively indicate that CBSE is working to strengthen defenses and validate that the affected components do not create further security risks.
